Let n be an integer. Prove the statement "If n² + 2n + 10 is odd, then n is odd." Make sure to include the introduction, body, and conclusion. Clearly state your reasoning for all statements and use a two-column proof for the body whenever possible. You should include an intro, body (in two column format), and a conclusion. a) Prove the statement using a proof by contrapositive. b) Prove the statement using a proof by contradiction.
